Abstract:

The principal instruments and facilities are described with special emphasis on new construction or modifications. This equipment includes two high dispersion grating spectrographs, two types of patrol spectrographs, ground- based, aircraft borne and balloon-borne infrared spectrometers, a scanning spectrometer for the visible and ultra violet regions with memory unit, two types of photometer for the study of twilight alkali emissions, a Michelson interferometer for the near infrared region and a temperature-measuring photometer for the measuring of auroral rotational temperatures. Also described are facilities for producing specialized interference filters, a source for the Vegard-Kaplan bands, intensity standards for absolute brightness measurements of aurora and a system for obtaining all-sky photographs through interference filters. There is also a brief description of two rocket borne photometers which are under development. Twilight airglow and dayglow measurements, observations of auroral emissions, of the night airglow and of auroral temperatures are discussed. A study is described of the possibility of measuring atmospheric temperatures using the vibrational ratios of N2 bands. New quantitative measurements of the Vegard-Kaplan bands in the second positive bands of N2 with the photo electric scanning spectrometer and memory are described.
